SAVING IN SIGNATURE TOOL
When using fill and sign in big PDF files the save feature almost doesn't work. The only way to save without freezing Acrobat is to exit fill and sign and then save.
Thanks for reporting the issue. Do you encounter this issue with every PDF file or only certain type of large sized file.
Can you try editing the file and then save it and check if it freezes. Also it will be great if you can share a sample file with us.
